Patented' Ang. 29,1935 A i were' claims. (C1. 'e 15e- 39) v The-.present invention relates-t0 a screen construction and more particularly to an automatically operated screen or iilter carried bythe window sash. u A Y Among the objects` of 'the 'present invention is the "provision of anovel construction of screen or filter adapted to be automatically adjusted by a raising or lowering ofthewindow sash.

Another object of thejinvention is the .provi-vv Vsion-of a novel screen and filter. and of means for mounting or anchoringran end thereof to the baseof the window.

A further object ofthe invention is the provision of anovel .casing for housing a rolled-up screen or lter Vwithin the lower rail of a window sash whereby when the sash is raised, the screen or lter automatically replaces the glass, thus permitting light and air to pass therethrough but preventing the entrance of insects, etc. f

A still further object is to provide a novel casing for housing an extensible screen within Vthe Window sash, said casing being readily assembled, removed from or replaced lon the sash.

Yet another object of the invention is the provision of acombined screen and housing therefor which can be assembled, removed cr replaced as a unit, in a windowl sash or frame.

Further objects are to provide a construction of maximum simplicity, eiciency, economy and ease of assembly and operation, and Such further objects, advantages and capabilities aswill later more fully appear and are inherently possessed thereby; l

The invention further 'resides in the Yconstruction, combination and arrangements Vof parts illustrated in the accompanying drawing, and' while I have shown therein a preferred embodi- Y ment, it is to be understood-that the same is' susceptible of modiiication and change, and comprehends other details, arrangements of parts, featuresV Vand constructions without departing from the spirit ofv the invention. v

In the drawing:

Fig.. 1 is a view in front elevation of a window construction provided with the novelscreen and filter unit. Y

Fig. 2 is a View in horizontal cross section taken in a plane represented by the lines 2 2 of Fig. 1;

Fig. 3 is a View in vertical cross section taken in a plane represented by the lines 3-3 of Fig. 1,;

Fig. 4 is a view similar to Fig. 3, but disclosing the sash in lowered position; v

j Fig. 5 is a vievv in vertical cross section taken in a plane represented by the line 5 5 of Fig. 4;

'Fig 6 is a View in vertical cross section of a locking means for locking the'screen and its -cas-..

ing to the lower ,sash railtaken on the line 6--6 of Fig.r3;` v. a Fig. '7 is aview in vertical cross section through a .means for attaching-the lower end ofthe screen l to the base ofthe window.r

Referring more particularly tothe disclosure in1 the drawing, the window frame. comprises rside jambs i and 2, a head jamb 3l and a-sill14 pro-N vided with a stool 5.- `Slidably mountedwithin the Window frame is anupper Sash and a lower sash Vl.

stocdthatthe samemaybe constructed of `Vwood or any other suitable material.

' The lower sash l is provided with a channelrshaped rail 3 open at its bottom and. connected to the side rails 9 and I0 of this sash by means of end plates i i and i2, as `by welding, rivets, screws or the like.A vSuitably mounted in the channelshaped rail 8 is a casing or housing for an eX- tensible screen and filter I3 composed of wire mesh, cloth or the like.

The window and yits, frame, are prefer-f ably iormed of metal,` although'it is tof be under-L lol rail, :and to retain `this casing in position, the v invention comprehends suitable retaining means comprising a plunger or buttonill having an enlargement iB sliding in a boss i9- formed in the side M of the casing. A spring 2) seats against one end of the enlargement I3, and itsother end seats against a removable closure' or Vcap A2l permitting the assembly and removal of the plunger and spring. In theV inner side of the sash rail 8 adjacent the side M of the casing are provided openings 22 into which the plunger extends. VIt

will be readily appreciated that when the casing is slipped into position and the plungers' come into alignment With or coincide with the openings 22, the springs 20 will force these plungers through the openings and lock or` anchor the lcasing in position. When it is desired to remove the outer side of the rail 8 and limit the insertion of the casing into the sash rail.

The screen and filter i 3 has its one endattached to a tubular roller `2,3 and its lower end is adapted to be attached to retaining buttons or fastening devices 24 mounted on the's'tool or base of the The lower end or n window frame. Although I have shown three of these retaining fasteners, one at each end of the stool and one in the center, it is to be understood that any desirable number may be employed to suitably retain the lower end of the screen in tight engagement with the stool. Within the tubular rollerl 23 is mounted a shaft 25 about which is coiled a spring 2S. One end of this spring is suitably attached to the shaft or rod 25 and the other end is suitably attached or embedded in one of the end bearings 21. 'Ihe ends of the rod or shaft 25 are seated in the opposite end Walls 28 and 29 of the casing housing the screen.

In order that the screen and lter I3` may be raised and lowered as the lower sash is raised or lowered, and to permit the lower sash to be completely closed, the side wall I4 and the base I6 of the casing are formed with a longitudinally extending opening or slot 3B of a length conforming to the Width of the screen. Thus it will be seen that the sash may be readily lowered or raised without any binding on the screen.

From the above description andthe disclosure in the drawing, it will be readily apparent that the invention comprehends a novel screen and lter construction which may be cheaply manufactured and readily assembled in a Window sash. In Windows now in use, it rmerely requires the replacement of the lower rail where it does not have a contour adapted to receive the screen and its casing, or the screen and its casing may be assembled in the sash at the factory. The novel construction permits a complete enclosure of the operating mechanismfor the screen and in which the enclosed screen is not open to the elements.

Havingthus disclosed the invention, I claim:

1. A window screen and filter construction for a window sash provided with a hollow lower rail, an extensible screen adapted to be anchored on the base of the window frame, and a removable casing in said rail adapted to house said screen.

2. A window screen and lter unit for Windows provided with a sliding sash, comprising a caing adapted to be carried by the sash, an extensible screen and lter housed within said casing, and spring-pressed retaining members for detachably holdingr the casing in proper position.

3. A window screen construction for a window sash provided with a hollow lower rail, comprising a casing and an extensible screen within the easing, said casing being insertible between the sash rail Walls and detachably` carried by the sash.

'4. A Window screen device for a window sash comprising spaced apart walls depending from said sash, and a casing adapted to be oonnected to said wallsand to extend across the bottom of the space between the walls, said casing adapted to hold a rolling screen.V

A window screen unit for a Windowfsash provided with spaced apart depending walls, Com,- prising ay casing adapted tobe detachably connected to said walls and to extend across the bottom of the sp-ace between the walls, said casing adapted to vhold a rollingscreen, and yielding retaining members for holding the casing in proper position relative to said-walls.
